ADJUSTABLE STAND.

d sease.

To all whom it may concern:

Be it known that I, WILLIAM H. MARTIN, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Improvement in Adjustable Stands, of which the'following is a specification.

This invention relates to certain new and useful improvements in stands used by carpenters, plasterers and paper-hangers, the object being to provide a stand on which a platform can be placed, in such a manner that the same will be supported so that all danger of thesame tilting is prevented.

Another object of my invention is to provide a stand with adjustable legs, whereby the same can be adjusted to any height desired, andv locked in its adjusted position securely, so that all danger of the same collapsing is revented.

- A still urther object of my invention is to provide a stand which is exceedingly chea and simple in construction, and one wh ic is very strong and durable, the parts being so connected that when in a set u position, a very rigid stand will be forme With these and other objects in view, the invention consists in the novel features ofconstruction, of parts, hereinafter fully described and pointedout in the claims.

In the drawing forming a part of this specification: Figure 1 is a erspective view of my improved stand, part y'broken away.

Fig. 2 is a longitudinalsection through one zontal section.

In carrying out my improved invention I employ a stand A WhlCh is preferably formed of pipe comprising a central coupling member B having oppositely disposed branches B, to which are connected horizontal pipesections C, said pipe sections being threaded into the coupling member -B, and having threaded outer ends, on which are mounted elbow couplings D, in which are threaded the upper ends of telescoping legs E. The legs-E are formed of twosections, one fitting within the other, the outer section E having a series of threaded bores F adapted to receive a set screw G carried by a threaded bore H -formed in a collar 'H, arranged over the outer sectionfor clamping Specification of Letters Patent.

in their adjusted the sections of the legs each other, whereby positions in respect to the horizontal members of the stand can be adjusted-to any height desired, or any one of the same adjusted independently, so as to allow the stand to be used onan uneven surface.

can be readily taken apart for shipping and small space.

Havm thus fully described my invention, what I c aim as new and desire to secure by .Letters Patent is 1. A stand of sitely disposed branches at right an les to each other, horizontal pipes secured in said branchesprovided with threaded outer ends, elbows secured on said threaded ends, leg sections secured said elbows, lower leg sections arranged over the first mentioned sections having aseries of threaded bores, and a collar surrounding said lower section carrying a set screw adapted to extend through said threaded bores and the upper sections of said legs for loc ing the same in their adjusted positions.

2'. As a new article of manufacture, a support or stand com rising a couphng member having opposite y disposed branches extendin by said ranches, elbow con lings carried by the ends of said pipe sect ons, legscarried bythe elbow couplings, said legs comprising a pair of telesco outer sections being provi ed with threaded bores, and collars carried by the outer .sections carrying cl through the bores of the outer-sections, an engaging the inner sections for locking the sections 1n their adjusted positions in respect to each other.
